My invention has for its object improvements in warping or reelingmachines adapted to reel any fibrous material for constituting the warpin the weaving of a fabric.

A primary object of my invention is to associate with the usual warpingreel or drum carried on a wheeled frame with a separate headpiececarrying all the controlling members adapted to ensure the rotation andtranslationalshifting of the reeling drum. This arrangement of separatecontrolling means on the head-piece allows an easy removal and change ofthe reeling drum as soon as it is loaded so that there is not time lostin such a change of reel while at the same time the cost of thesubstitute reels reduced to the actual reeling means is much lower thanheretofore.

According to a further object of the invention, the head-piece is alsoprovided with various controlling members in addition. to those referredto, said controlling members cooperating with the meters giving out thenumber of revolutions of the drum and with further meters for measuringthe shifting movements of said drum and also with the braking andclutching members.

The invention provides also for a motor carried by the head-piece andcontrolling through a clutch the Oldham or the like coupling meansdriving the drum around its axis.

According to a still further object of my invention, the reel or drumbraking means are constituted by a braking band directly engaging thedrum and controlled through the head-piece.

My invention also provides for a duplicate system of meters giving outthe location of the reel or drum along its axis, one of the elementarymeters providing a rough measurement and the other a highly accuratemeasurement.

Furthermore, the thread guiding reeds are fed through the agenc of acarriage that is automatically shifted transversally with reference tothe drum axis in proportion with the increase in diameter of the threadcoiled over said drum.

According to a further feature of the invention, the revolution meterautomatically stops operation after a predetermined number ofrevolutions Which removes the objectionable efiect of any omission inthe operation of hand-actuated clutches as provided heretofore inreeling machines.

Further advantages and features of m invention will appear in thereading of the following description of a preferred embodiment orf'saidinvention that should be considered only as an example withou any bindng sense Intha-a companying drawings illustrating said embodimen Fig. 1illustrates the complete warp frame in elevational view as seen from thebobbin board.

Fig. 13 is a plan view showing the location of the creel with referenceto the actual reeling means fed thereby.

Turning more particularly to Figs. 1, 2 and 13, it is apparent that themachine comprises a reeling drum 2 permanently secured to a carriage .3mounted on four swivelling wheels allowing both an easy displacementover any flat area and an accurate guiding over the rails 5. Said drum 2is removably associated with a head-piece I also mounted on the rails 5and carrying the various controlling means ensuring the rotation and thelongitudinal shifting of the drum as well as the controlling means forthe brake acting on the drum and for" the clutch operativelyconnecting'said drum with the head-piece. {said head.

piece also carries as disclosed hereinafter various checkingapparatuses, and meter 'Ifhe .reed -carrier 6 shown more particularly incross section in Fig. is anchored to the ground along the axis of thebobbin board III (Fig. 13) and includes a movable carriage adapted tomove perpendicularly to the axis of the drum under the action of a rackand pinion system 46-41 through the progression of the drum carriage 3as the latter moves longitudinally over the rails 5 as will be disclosedalso hereinafter.

The drum 2 that actually carries no control means is entirely closed andis made of metal sheet and appears as a large so-called bottle spool.Its capacity is considerable. It is provided with an adjustable brakesystem described provide for a secure connection between the headpieceand the drum I.

The head-piece may move over the rails 5 anchored in the groundperpendicularly to the axis of the creel through a sort of towing actionexecuted on a rack I4 also anchored in the ground. Said head pieceincludes a driving motor 8, a friction clutch I5 (Fig. 3) actuated by an'electromagnet, a pinion 9 for shifting the head piece over the rails 5and the speed of which with reference to the speed of rotation of thedrum may be increased when desired to ahigh rate, a meter I 0 measuringthe number of revolutions of the drum and adapted to controlelectrically the stopping of the machine, two dials adapted to measurethe shifting of the drum with reference to the creel and electromagnetsnot illustrated actuating the band brake of the drum,

2. control lever I2 for rapid right hand and left hand displacements andlastly the electric apparatuses required for controlling from a distanceand stopping of the different mechanisms forming the machine.

The motor 8 controls through the belts I00 an intermediary shaft I6 onthe head piece, which shaft I6 rotates permanently. Said shaft (Fig. 3)carries for rotation therewith a sprocket wheel I'I driving the rapiddrive gear as described hereinafter and it also carries a pinion I8mounted loosely on said shaft I6. Said pinion is held between twoflanges I9 and I9 forming the above mentioned clutch, that arelongitudinally keyed to the shaft I6 and of which one is axially movableand is constantly urged against the pinion I8 by an adjustablecompression Spring 20. Said flange is submitted through the agency ofthe lever 2| to the action of an electromagnet HQ,

and of a return spring 22 (Fig. 6) whereby when the electromagnet isenergized the compression spring is released while a sliding connectionis provided between the driving shaft I6 and the pinion I8 through theflange IS considered. The pinion I8 drives a toothed wheel 23 on themain control shaft 24 of the head piece. Said shaft includes on theoutside ofthe head piece an Oldham coupling I3 through which said shaftdrives the drum 2.

The shifting of the drum carriage and head piece over the rails 5 isobtained through the sprocket pinion 25 keyed to the shaft 24 and thatdrives through a chain or the like positive mechanism a gear system28,'a swing frame carrying gears 293fl3I-32 controlling a worm that"through the agency of a worm wheel 34 drives the pinion 9 that is keyedto the same auxiliary shaft as said worm wheel 34. Said pinion 9 engageswithout any clearance the rack I4 that is anchored to the ground throughit two ends.

To each revolution of the drum corresponds a displacement or shifting ofthe head piece and of the drum, the importance of which depends on thegears 29-30-3I-32 that have been chosen.

The displacement of the head piece is measured by a meter I I with twodials of conventional type as shown in Figs. 1, 2 and 8, said meterbeing controlled through the worm shaft 35 through the agency of a pairof bevel gears 36 and a connecting shaft I0 (Fig. 12). Said shaft drivesthe handsover the meter dials. The left hand dial (Fig. 8) carries ascale ranging from zero to 1,000 millimeters and that on the right handbetween zero and 100 millimeters. The smaller hand IOI of each dialgives out the accurate positioning of the head piece and carriage systemwith reference to a stationary point, i. e. in the case considered thereed carrier. These two hands IGI allow obtaining very accurately theposition of the line joining the cylindrical and conical parts of thedrum with reference to the tooth of the reed engaged by the firstthreads of the section. The larger hand I02 of each dial gives out theamount by which the carriage and head piece system is shifted withreference to the reed for each section. Through construction the smallhands IOI are not adjustable while the larger hands are adapted to bereturned to zero at the beginning of the operation of each'section so asto indicate the exact displacement of the system. To this end,

:' they are driven through a small driving clutch allowing said returnto zero as soon as a suitable mill knob is actuated. During operation,the larger hand I02 of the right hand dial moves ten times more quicklythan the hand I82 on the left hand dial, which allows an accuratereading of the displacement of the system that may be estimated with anerror less than 0.25 millimeter, the right hand dial giving out largescale indications while the left hand dial provides the rougherindications Each dial is provided with an adjustable mark 37 theposition of which on the dial scale may be modified as required. Thesetwo marks are adjusted in accordance with the exact breadth of thethread section on the drum. The hands or pointers may thus be brought toregister with the scale graduations corresponding to the breadth of thethread sections to be reeled starting from said marks.

The main control shaft of the head piece carries a pinion controllingpositively a transversal shaft that through the agency of a worm andworm wheel gear controls the meter l0 recording the number ofrevolutions executed by the drum. This meter I 0 (Figs. 9 and 10) of thecylinder type is constituted by a cylindrical body carrying a scale andprovided with a helical groove I03.

Removable keys 40 of which one is shown in position in Figure 9 on thecylinder act on a releasing slide 33 that produces a stopping of thewarp frame after a predetermined number of revolutions. To produce sucha stopping, the slider 38 that is actuated by the keys controlssimultaneously two electric switches. One of the switches S illustrateddiagrammatically in Fig. 9, switches off the current passing through thecircuit C feeding the coils controlling the clutchand brakingcontact-pieces and produces thus the immediate stopping of the warpdrum. The second switch closes the electric circuit passing through asignalling lamp lying in front of the operator inside the box orpanelcarrying the control knobs for the machine.

The meter I0 includes as special features a double automatic clutch I04associated with a return to zero handwheel M for driving the cylinder I0forwardly or rearwardly without the operator interfering and further therocking Slider 38 mentioned hereinabove that allows a rapid return tozero.

The automatic clutch I04 operating through rollers and cam slopes is notnovel per se but heretofore the clutch operating for forward progressiondid not allow a perfect connection between the cylinder of the meterwith its drive. As a matter of fact, in prior art, the cylinder wasliable to slide in the direction of progression quicker than its drivingmember under the action of any vibration of the system. Such untimelydisplacements are generally inconsiderable, of the order of a fewangular minutes but they are generally frequent and produce throughtheir repetition an important shifting that may correspond to a finalerror equal to one revolution of the drum. The second series of rollersand cam slopes incorporated to the clutch I04 removes such a drawbackand provides for an accurate positioning of the cylinder in bothdirections of rotation with reference to its driving member.

The rocking slider 38 slides freely over a fluted shaft 39 and rotatesin unison therewith by reason of the presence of a connecting key. Saidshaft carries a projection forming a current breaking switch between theterminals of the circuit. A return spring urges said projection in adirection such that the projection restores electrical connectionbetween the terminals and at the same time the slider is urged by theshaft into the helical groove I03 of the meter cylinder I0.

During operation, the rotary cylinder drives the slider 38 along a lineparallel to its axis and the openings I05 in the cylinder groove pass insuccession underneath a boss provided on the slider 38. When a key 40(Fig. 9) fitted in one of said openings I05 appears in the path of theslider. the latter rocks to a certain extent together with the shaft 39and the projection thereon so that the circuit is broken and the machinestops.

In order to avoid the necessity of returning the slider into itsstarting position by operating the handwheel 4| in the oppositedirection which is long and tedious, the rocking slider 38 may beshifted axially of its guiding shaft after a raising movement thereof.Thusat the end of the metering operation, the slider may be rockedout ofthe groove by hand so that its tail'end may move out of its helicalgroove I03 after which it is slid axially as stated alone its shaft toregister with the starting portion of the groove I03 into which it iscaused to enter through a reverse rocking movement. It is thensufficient to make the cylinder rotat through a fraction of a revolutionin order that a stop provided on the cylinder may abut against theslider exactly in the zero or starting position thereof.

The head piece also carries a quick operating device for shifting. thewarp frame over the rails 5 which is provided as follows (Figs. '6 and'7) The auxiliary shaft I6 controlled by the motor carries a sprocketpinion I'I already mentioned that through the agency of a chain controlsa speed reversing gear constituted by two pinions 4343 rotating inopposite directions in apermanent manner (Fig. 6).

Coaxially with said pinions, a shaft 60 carry- 6 ing a'double cone 42keyed thereto controls in either direction and at a high speed the abovementioned worm through the agency of the gear wheels 44. The worm 35transmits, as already disclosed, its movement to the worm wheel 34 andto the pinion 9 producing thus the rapid displacement of the head pieceover its rails. To produce a connection in either direction, the shaft60 carrying the cone 42 is adapted to move longitudinally of its axis.This displacement of the shaft 60 is controlled through an outer leverI2 (Figs. 1 and 2) that controls the angular position of a shaft 53carrying at its end a pinion 6!. The latter meshes with a rack cut in acollar 62 servihgas a bearing for the shaft'60 and adapted to moveaxially in unison therewith. Thus, the

displacement of the rack under the action of the lever I2 produces aclutching which provides a rapid movement of the head piece in eitherdirection.

The head piece thus described is coupled with the drum carriage 3through two key coupling means. Therefore when a warp drum'is finishedthe operator may easily and rapidly return the head piece into itsoriginal position in which it is ready to receive the next empty drum inplace of the finished drum.

Each drum carriage is constituted by a frame 3 of shaped iron entirelywelded and to which are secured four wheels 4 adapted to assume anyangular setting and that may roll either on the same rails as the headpiece or on the ground. Said carcase carries the drum 2 constituted by awelded system of iron sheets and including at its end a cone I2 ofpredetermined angle made also of sheet metal. On the side of the drumfurthest removed from the cone is mounted a brake "I3 adapted to operateboth during winding and unwinding (Fig. 11). V

In said brake, thepoint 56 is that at which the brake band 51 is securedto the drum carriage 3 and the movable securing end 58 is carried by asquare-shaped lever 59 tensioning the band 51 under the action of thespring 59 acting on said lever 59. Said bell crank lever is controlledby an electromagnet M on the headpiece and releases the drum or brakesit during the warping operation.

7 This bell crank lever allows the following standard advantages:

(1. Increasing the action of the brake when the drum rotates as shown bythe arrow 0 during the warping so as to provide a speedy and energeticbraking.

1). Reducing the action of the brake when the drum rotates in thedirection'of the arrow E during the sizing or dressing during whichoperation it is carried along by the unwinding sheet of threads. In thefirst case, there is a self fastening operation and in the second case aself unfastening operation.

The machine includes lastly a reed carrier I; (Fig. 5) that isindependent and anchored to the ground.

Each drum carriage is provided along and to the front'of .the frame onthe Side facing the creel III (Fig. 13) with a rack 46 meshing with thepinion 41 (Fig. 5) projecting beyond'the stationary reed carrier 6.Inside said carrier, said pinion drives a shaft 48 that throughthe-agency of a free wheel and of a clutch drives in its turn a pinionmeshing with a rack 50 rigid with the carriage to which are secured thereeds 5I-5I and the thread guiding roller 5%.. A

counterweight 53 suspended from the chain 54 the other end of which issecured to said carriage 1 urges the latter forwardly towards the sidecorresponding to the warp drum. An operating lever 55 releases the reedcarrier I with reference to its control shaft. At the beginning of thewarping of a section H (Fig. 13), the reed carrier. 1 is locatedcompletely to the front with the thread guiding roller 52 very near thedrum. During the warping, the drum carriage moves under the control ofthe head piece and its rack 46 controls consequently the rotation of thepinion 47 and shaft 48 and thereby displaces the rack 30 so as to makethe carrier 1 recede in proportion with the accumulation of threads onthe drum 2. In other words, considering a triangle the hypotenuse ofwhich is the generating line of the conical end of the warp drum, thelonger side the extent of they lateral shifting of the carriage 3 andthe small side the extent of movement of the reed carrying carriage I,it will be noticed that the ratio between the shiftings of the twocarriages 3 and 1 is such that the thread guiding roll 52 may followexactly the accumulation of threads over the sloping cone of the warpingdrum. This provides an accurate guiding of the sheet of threads wherebyit is possible to position the threads in a very uniform mannerthroughout each section.
